Specification of Letters Patent.

Patented Sept. 18, 1906.

Application led August 26, 1905. Serial No. 275,878.

To a/ZZ ZIJ/wm it muy concern:

Be it known that I, WILLIAM SAMUEL PMM, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedGas-Burner, of which the following is a full, clear, and exactdescription.

The invention relates to that class of gasburners commercially known asincandescent arc lights or cluster burners, in which a number of burnersusing a VVelsbach mantle are grouped together to produce a .relativelyintense light.

l The invention is applicable to both interior and exteriorillumination.

The principal object of my invention is to provide means for increasingthe illuminating power of the gas and rendering the combustion thereofmore perfect than in burners now commonly used, to which end I provide apeculiar gas-heater arranged over the burners, from which heater the hotgas is conducted down to the mixing and burning devices.

It is also an obj ect of the invention to improve the devices forregulating and mixing the air and gas so that the Inost effectiveresults may be obtained.

A further object is to c'onstruct the device so that by simpleadjustment it may be converted into either an interior or exteriorburner--that is to say, a burner adapted for use in or out of doors, asdesired.

The invention involves various other features of maior or minorimportance, all of Reference is had to the accompanying, drawings, whichillustrate as an example the` preferred embodiment of my invention, inwhich drawings-'- Figure 1 is a perspective view showing the inventionadapted for indoor illumination. Fig. 2 is an enlarged sectional view ofone of the burners, as shown in Fig. 1. Fig. 3 is a section on the line3 3 of Fig. 2. Fig. 4 is a detail sectional view of the upper end of themantle-sup ort showing the manner in which the removalilemantle-supports are arranged. Fig. 5 is a detail view of one ofthemantlesupports. Fig. 6 is a sectional elevation showing the lightadjusted for exterior or outof-door'illumination. Fig. 7 is an enlargedsectional view of the gas check or regulator shown in Fig. 6. Fig. 8 isa detail section on the line 8 8 of Fig. 6, and. Fig. 9 is a detailsection on the line 9 9 of Fig. 7.

As best shown in Fig. 6, the gas is supplied to the burner from a tube410, which extends into a heating-drum 11 and has a stop 12,

forcing the gas to pass out of the tube 10 through openings 14 in saidtube and into the heating-drum. Below the stop 12 the tube is providedwith openings 15, through which the gas renters the tube. Said drum 11has tubes 16 passing through it, these tubes being intended to conductthe hot gases from the burner to the drum, thus thoroughly heating thegas therein. Below, the drum 11 the tube 10 supports a spider 17, whichis adjustably fastened by setscrew 18. Said spider inturn sustains anannulus 19, 'with which the shade 20 of the lamp is engaged. The annulus19 also supports the .chimney 21, which is tubular' in form and whichrises from the annulus, wholly or partly inclosing the drum 11, so as toenforce the heated gases from the burner to passthrough, ascontradistinguished from around, the drum. The gas supplied through thepipe 10 is therefore caused to circulate through the heatingdrum andthence back into the pipe 10, through which the gas passes downward tothe burner proper.

According to the arrangement shown in Figs. 1 to 5 the tube 1() passesdownward into Acommunication with a tube 22, which is fitted with avalve 23. Preferably this valve has a wheel or its equivalent 24connected thereto, and to said wheel dependent chains 25 are joined, soas to permit opening or closing the valve 23 from below the gas-burner.

Said tube 22 extends upward into a gas- I chamber 26, which, as shownbest in Fig. 8, is preferably of cruciform construction, though this isin no sense essential. The gaschamber 26 lies alongside of the tube 10and is braced by means of a clamp 27, engaged with an ear 28, projectingfrom the gas-chamber. 29 indicates the usual pilot-frame tube whichextends from the gas-pipe 22. Rising from the central part of thegas-chamber 26 and screwing into an orifice in the top thereof is astandard pipe or tube 80. Preferably this tube communicates with theinterior of the gas-chamber, so as to increase the heating-surfacethereof. At its upper end the tube 30 is provided with a head 31, (bestshown in Fig. 4,) and is provided with a number of sockets 32. In thesesockets the bent IOS ends 33a of the mantle-supporting arms 33 areloosely engaged. By this arrangement the mantle-supporting arms areremovably yet securely held in place. Said arms project outward from thehead 31 and carry the mantles 34, as shown in Fig. 1. The tubular part30 is also important in that it prevents burning away by the heat of thellame.

According to the construction shown in Fig. 1 the burner adapted forexterior illumination is provided with four burners proper, all of thesame construction and one of which is illustrated in detail in Fig. 2.Said burners proper comprise `a gas-tube 35, communieating with thegas-chamber 26 and formed at its upper end with an outlet-orifice 36,which is commanded by a needle-valve 37. The stem of the valve isthreaded in the tube 35 and projects downwardly below the same. Saidstem has a head 38, by means of which the valve may be adjusted, andpreferably this head is formed with a kerf, facilitating the applicationof a screw-driver or similar tool. The tubes 35 are bent slightly in theform of an elbow, so as to facilitate the abovedescribed l-arrangementof the needle-valve 37. Fastened to the upper end of the tube 35 is aforaminous gage 39, which is cylin dric in form and loosely receivesasimilar gage 40, attached to or forming part of the contractedburner-tube 41. Asis shown in Fig. 3, a setscrew 42 is provided to limitthe relative j turning movement of the parts 39 and 40,

and byadjusting the gage 40 the orifices in said gage and in the gage 39may be placed wholly or partly in registry, so as to regulate the supplyof atmospheric air drawn into the burner to be mixed with the gasentering the orifice 36. The contracted tube 41 'of the burnerterminates in an enlarged part 43, over which the usual screen 44 isarranged. The mantle 34 hangs over the burner proper, as will beunderstood from the prior art and as is illustrated in the drawings.

The heated gas passing from the drum 11 downward through the tube 10enters the gas-chamber 26 through the tube 22, the valve 23 being openfor this purpose. Said gas is maintained in the chamber in a heatedcondition, the heat being kept up by the j uxtaposition'of the chamberto the burners and by the heating effect of the before-described tube30. The check-valves 37 being properly adjusted the heated gas entersthe burners through the orifices 36, it being well mixed with theatmosphere in proper proportions, according to the adjustment of theparts39 and 40, and the mixture passing through the contracted tube-41,after which it expands in the enlarged end 43 and is burned as it isemitted from the gauze cap 44, the heat of combustion raising the heatto incandescent and the-cluster'of burners giving off an intense light.

tion, as shown in Fig'. 6, is provided with iive burners instead offour, the fifth burner being Vsustained by the usual wires 45, which arefastened to the burners, as shown in Fig. 6. Figs. 6, 7, and 9 alsoillustrate a second inanner of constructing the device for regulatingthe air and gas supply to the burners. As shown best in Fig. 7, eachburner has a connection 46 with the gas-chamber 26, and thesecommunicate with two tubular standards 47. (See Fig. 9.) Said tubularstandards 47 in turn communicate with a tube 48, in which a plug 49 isscrewed. This plug is provided with an orifice 49a, which is commandedby a needle valve 50, and said valve has its stem threaded in the loweror bottom wall of the tube 48. Secured to the lower or exposed end ofthe stemv of the valve 50 is a thumb-wheel 51, which lies between thetube-standards 47, so that it may be conveniently grasped by the fingersof the operator. In this manner the thumb-wheel 51 of the valve isexposed and the gas is conducted around the sides thereof through thetubular standards 47. The gas is discharged through the orifice 49a intothe burner, which is essentially the same as previously described.

It is pointed out that the gas and air regulating devices, shown,respectively, in Figs. 2 and 7, may be interchanged at will-that is tosay, the device shown in Fig. 7 may be applied instead of the deviceshown in Fig. 1, and the device shown in Fig. v1 may be applied to thedevice shown in Fig. 7 instead of 4the mixing and regulating devicesthere illustrated.
